The' Schedule referred to in these Letters Patent and making parl: of the same.

To all whom it may concern Be it known that I, WALKER OLD`s, of Albany, in thecounty of Whitesides, and State of Illinois, have invented a new and useful Improvement in .Brick- Machines; and` I do hereby declare that the following is a full, clear, and exact description of the same, referencebeing had to the annexed rh'awings making pait of this specification, in which Figure 1 is a top view.

Figure 2 is a bottom view.

Figure 3 is an elevation.

Figure 4 is a vertical central section.

Figure 5 is a perspective view of the mechanism connected with part of the press.

Figure 6 is a perspective view of the brick-moulds.

Figures 7, 8, 9, and 10 are views of parts of the machine, to be particularly hereinafter described.

'The same letters in all the figures are used to indicate identicalpalts.

My improvements relate tcmachines for pressing brick, and their' character will fully appear from the following specification, and the claim thereto annexed.

The machine is supported upon a strong frame adapted to the mechanism. This flame is composed of sill-pieces A, and l transverse beams A, vertical posts A2, 'and upper frame-work A3. A

At A4 there are vertical iron rods, passing entirely through the frame, with nuts, by which the whole frame is tightly bound together.

A horizontal 'anie-work, at A5, supports the Hoor of the pug-mill and the greater portion of the operating-mechanism, and A. is the bridge-tree, on which is placed the step for the toe ofthe main driving-shaft B.

The power may be applied to the upper end of the main shaft by a beam, B', when horses are used, or by means of a band and pulley, or a system of gearing, when othenkinds of power are to be applied.

The pug-mill is within the frame, and the -clay is tempered by means of arms attached to the shaft B, which, being of ordinary construction, are not shown.

.The sweeps C, attached to' the shaft immediately above the oor of the pug-mill, areused for the purpose of sweeping the tempered clay outwards, and towards the presses.

. Below the pug-mill an arm, D, with a Asegment cfa bevel-wheel attached,'is fastened to the main shaft B, with the revolution of which its cogs alternately engage similar bevel-segments, attached to arms adjustably fastened to the horizontal shaft E', so that an oscillating revolution is given to said shaft, as'the cogs. of the segmentD alternately engage those ofthe segments E E, moviugfthe shaft as far as their eogs engage. These arms are adjustably attached, so that as the cogs become worn, the segments maybe kept in gear by moving the segments E nearer to the shaft B.'

On the outer ends of the shaft E are placed segments of spur-wheels, F, each being about a quadrant in form.

The teeth of the spur-segments F engage racks G on the base of the metallic moulds Gr, Aso that as'the segments F oscillate from side to side, they shall throw the moulds G from side to side of the machine. These moulds are two-thirds of the length of the frame, so that as the moulds are thrown from side to side,ouehalf the brick-moulds shall be opposite to the press to hefilledwith clay, and the vothers opposite -plungers arranged 0n each side of the press, which will force out the bricks contained in the moulds,l so that while half the moulds are being illed, the other half are being delivered of the bricks.

The pressing-mechanism is constructed and arranged 'as follows:

H is a bevel-wheel on the upper end of the main shaft, and driving two bevel-piniohs, I l, which give revolution to the cranks Il.

The pitman I2 is attached to the crank-piu above, and below to the vertical pressing-head K, which moves up and down iu ways.

These heads, K, being raised into the pug-mill, the clay is forced under them by the sweeps O, and as they descend they force the clay down in front of the horizontal press-heads N. Y

The vertical press-head K has two arms, tending upwards, asshown in iig. 3.

Slots are cut in` these arms, toreceive the ends of the oscillating levers L, which are centrally pivcted to the frame, and connected, by the pitman L1, to the knife L.

This knife has thus a reciprocating motion, the reverse of that of the press-head K, and is used to cut the clay immediately behind the moulds; after theyhave been-filled by the press. These parts are duplicated, there being a press on each end of the machine.

The rods L and L1 are connected by .a wooden pin,

L ,whieh forms their pivot, so that if a knife shouldl encounter a stone, the wooden pivots would break, and thus prevent more seriousinjury to the machine.

The horizontal press-heads are' simultaneously operated by the cam M, attached to the shaft B.

The cam presses against friction-rollers, M2, attached to the press-heads N, above the iron plates N, which are rigidly attached to the press-heads.

In ord'er to counteract the lateral pressure of the cams against the press-heads, beams 0 are attached thereto, V(see iig. 2,) lying along the sides of the transverse beams of the press. i

Arms O1 are attached by round bolts to the beams O', and these arms have a rounded recess near the 'ends, to receive the lwrist-piu M1, projecting from the face of the cam. As the cam revolves, these wrist-pins come in contact with the edges'of'the arms O1, which are pressed against -the wrist-pins by the springs O2,

K2, ex-

until the wrist-pins enter the notches, when the cam, acting upon the arms O, will drawback the beams O and the press-heads N. When they have been drawn back, the pins are disengaged from the notches by means of the adjustable bosses'M, which will bear against the ends of the a1-ms. These bosses are adjnstably attached to the cam by set-screws passing through slots in the. bosses, sothat they may be Ireadjust-ed asthey become worn from use.

Connected with the press-heads N, which operate on the clay forcing it into the moulds, and arranged on each side of the latter, is a corresponding number of heads, N2, which, moving simultaneously with the press-heads, force the bricks from tbemonlds which have been first lled, and lre then shifted to the sides ofthe machine, alternately. M

Air-holes, shown' in figs. 3 and 4, are formed in the heads N2. The ends of these heads should be covered with a woven fabric to prevent adhesion.

Slots are cut in the verticall posts A2 A2 opposite the ends ofthe moulds, as shown in fig. 3, in order to permit the clay ca -rried onth'e ends to escape.

' Set-screws, G2, are passed through these posts, to form stops to regulate the throw of the moulds, as the sharp points of these screws will not catch the clay adhering to the ends of the moulds, as would be the case ifbroad surfaces were employed for this purpose.

lThe horizontal presses may he made either against a press-plate, Il', held in' position by a beam, l), secured to the frame, or reciprocating plungers may bc used to act from the outside' against the brick in the mould, simultaneously,with `the pressure of the horizontal press-heads from within.

Ihe heads Q are attached by lugs to the oscillating shaft Q1, ii'om winch arms Q2 extend downwards, which are fastened by a rod, Q3, to the reciprocating rods Q4, fastened to and moving with the press. The rod Q2 passes through slots in the ends of the rods 0*, and set-screws, passing through the ends of the Iods Q4, and bearing against the rod Q3, are used to regulate the citent of reciprocating motion to be given to the plungers Q.

p R-R are sliding boards, moving freely in vertical grooves in the frame-timbers, and supported on points It. Ihese point-s have a reciprocating motion, derived i'om the oscillating arms R2, (figs. 7 and 8,) which are centrally pivoted and acted upon by slots in the heads N2, so that asthe heads move forward to press the bricks out ofthe moulds, the points R1 will be retracted, thus disengaging the lower board R, which will fall 'behind the brick as soon as the heads N2 are drawn back, and the pointswill be again projected as the heads retire, so as .to support theV other boards R.

separate the bricks successively forced from the mould, and to carry them forward, by the action of the press, on to the revolving apron on which they are to be removed.

These boards may also be used to. carry the bricks to be baked in the yard, and when returned are inserted at 'the top of the frame.

S is an apron to receive the bricks as they are pressed from the inachine. Itffrnay be mounted on a frame supported upon wheels, so that the bricks may and desire to secure 2. The reciprocating moulds G, in combination with the oscillating segments F, and plungers N and N2, substantially as described.

3. In combination with the press-heads K, and arms K2, the lever L, rods L1, and knife L2, substantially as s'et forth.

4.. In combination with the knife L2, rods L1, and lever L, the wooden pins L, substantially as and for the purpose set forth.

5. In combination with the shaft B and press-heads N, the cam M, beams 0, arms O, springs O2, and wrist-pins M1, and bosses M2, substantially as set forth.

6. In combination with the reciprocating moulds G, tbe slotted verticalposts A2, and set-screw G2, substantially as described. p

7. rIhe combination of the reciprocating moulds G, and press-heads N, and plungers N2, arranged to operate substantially as set forth. p

S. The reciprocating moulds G, when so arranged as to receive the clay in the centre of' the machine, and to discharge the bricks alternately on each side-oi' the press, as set forth.

9. The combination of the press-heads N and Q, and parts Q1, Q2, Qland Q4, substantially as herein set'forth.

10. In combination with the reciprocating moulds G, and plungers N2, tbe'boards R, reciprocating points R1, and oscillating arms R2, snbstantiall y as set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
